This study will try to identify and treat feeder vessels in age-related macular degeneration. The macula is the part of the retina in the back of the eye that determines central or best vision. In macular degeneration, leaking blood vessels under the macula lead to loss of central vision. These vessels branch out tree-like from one or more feeder vessels. Instead of treating all the abnormal branching vessels, this study will try to find and close only the feeder vessels, thereby depriving the abnormal vessels of nutrition. The vessels will be closed with laser beam treatment.
